I want to run a batch file, perpetually which periodically "wakes up" and executes the same command over and over again. I could not see anything which suspend the batch file for 5 minutes.
I am sure I have overlooked sometihng.

With WAIT and @DTMARK[] you can get things done at "canonical" marks in time. For example, at the moment (13:35:12), WAIT @%DTMARK[5m] will provide a delay until 13:40:00. At the moment, WAIT has an omission that I'm intending to fix, namely, you can't interrupt it.

Stefano, perhaps others, I must add the ability to interrupt a WAIT. Of Ctrl-C and Ctrl-Break, which should be the one that ONLY interrupts the WAIT (letting a batch file continue without prompt) and which should propagate the signal so that ON BREAK, or the default "Cancel batch file" handler will also get the signal?
